' To all whom it may concimi: l

Be it known that I, THOMAS A. DE Vimiss, a citizen of the United tates,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Invertible Atomizer; and l do.

hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the saine, reference being had to theaccompanying drawings, and to the figures of reference marked thereon',which form a part of this specification.

My invention relates to atomizers, and

particularly to those of the compression type in which air is injectedinto Athe liquid re- -ccptacle to etlect a discharge of the liquid fromthe rece tacle ins ra r or va or form 'and in which the vaporizingaction is facilifated by the .discharge of. air past the discharge endof the liquid-tube. Considerable Objection has been made to the use ofthis form of atomizer due to the liquid escaping from thereceptaclethrough the air injection tube and into the bulb and alsothrough the airpassage surroundingthe liquid-tube when the receptacle isinverted or placed on its eide, thus prohibiting its use by' travelersand requiring care in always maintaining it in upright position when notin use. Numerous attempts have been made to overcome this objectionablefeature bythe insertion of valves in the tubes, which valves may beworked to close such tubes whenl desired.

This innovation, however, complicates and4 adds expense to the atnmizer,and is not entirely satisfactory' in all cases. l

The object of my invention is to Overcome theseobjections and,difficulties by arranging and disposing the aintube terminals in suchmanner relative to tbc receptacle as to effectually prevent the escapeof liquid from the' practicabilitv andcommercial valpe of atom- 2 is anenlarged section on the line ,o in

Fi l.

eerring to the drawing, 1 designates the liquid receptacle of usual orany suitable forni, the neck opening oit' which is closed by a suitablecap or closure-member i2. Piercing die cap or closure-member 2 in asuitl able manner are the air-injection tube 3 and air-exit tube 4e, theformer-of which has a compression-bulb 5 attached 'to its outcr end,While the' latter carries the spray-head 6 at its Outer end and incasesthe smaller liquidtube 7, the lower end of which extends to near thebottom of the receptacle. A simple and 'very efficientA manner' of'centering and securely gripping the liquid-tube 7 in the lower end ofthe tube 4 and at the same time providing openings for the admission ofair to said latter tube, consists in crimping the tube 4 for a shortdistance from its inner end so as to center the tube fr', securely holdthe tubes e andA 7 from relative longitudinal movement, and provideopenings 4l to the interior of thev air-exit tube, as shown in Fig. 2.

The inner ends of the 'air-tubes 3 and 4 `instead 4of terminatingimmediately after passing through the ca or closuremember 2, as isusually the case, extend down into lthe receptacle and terminate atYapproximately the center thereof, as shown. By disposing the tubeterminals in this manner, the liquid-, which is never placed in the re-vceptacle in suficient quantity to submerge the tube ends when in uprightposition, is permitted to flow around such centrally disposed ends whenthe receptacle is tipped or inverted, 'but is not enabled to submergethe same no matter in what position the recep tacle may be placed, thusrendering it practically impossible for the liquid to escapo from thevrece tacle except through the liquid-tube @an then only when theatomiaer is in use. .It is ap arent that this forms not only a simple anvery etlicient .fuzomizen` but also one which readily recommendsitseli:` to'travelers and to the users of such instruments generally,due to'the inability of the liquid contentsfthereof to accidentallyescape therefrom whentipped over or packed in .trunks or the like.

Having thus described my invention, l claim as new and ters Patent, is,-

l; In, a compression. atomie'er, a vessel, a

desire to secure by Letend extending" down within the vessel :ind

terminating near the center thereof, a liquidtube disposed Within the:iiieoutlet tube and having its inner end extended to neer the bottoniof tbe vessel, und ay spray-head Lissoeieted with 'the outlet ends 0Ipthe air-outlet and liquid tubes, substantially as described.

2. In an atoniizer, :i vessel, a closure inein-l ber for the neck of thevessel, airair-injection tube andan 'air-outlet tube piercing saidmember and the latter extending down with- 1n the vessel, a liquid-tubedisposed within oit' said vessel, an e piercing said ineinbei and i i Ii i i l I the air-outlet tube .With its inner end eX- tended to near thebottoni of the vessel, said nir-outlet tube having its inner end crimpedt0 forni eoirugzitions Which center the liquidt-nbe therein, rigidlygrip the liquid tube from longitudinal movement therein, und provideradial passages around the lqnid-tube for the admission of nir to' thenir-ontlet tube from. tlie vessel, Iind :i sprayliezid associated withdie nir-outlet and liq nid-tubes.

In testimony whereof I have hereunto signed my naine 4to thisspeciiicetion in the 'presence of two subscribing Witnesses.
